After analysis, this stored XSS could be used to elevate privileges from Editor to Admin. We believe that this vulnerability is rated at CVSS 7.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N). ### Impact An attacker can exploit this vulnerability to escalate privilege from editor to admin by tricking an authenticated admin to click on a link. ### Affected versions with HIGH severity All Grafana >=8.0 versions are affected by this vulnerability. ### Solutions and mitigations All installations after Grafana v8.0 should be upgraded as soon as possible. As a workaround it is possible to [disable alerting ](https://grafana.com/docs/grafana/next/alerting/migrating-alerts/opt-out/#disable-alerting)or use [legacy alerting](https://grafana.com/docs/grafana/next/alerting/migrating-alerts/opt-out/#staying-on-legacy-alerting). Appropriate patches have been applied to [Grafana Cloud](https://grafana.com/cloud) and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana. ### Timeline Here is a detailed timeline starting from when we originally learned of the issue.
